A further object is to provide novel forms of holders for the containerwhereby it can be used as a refill for the hollow handles of shavingbrushes, for cream dispensers and for toothpaste holders or the like.

A still further object is to construct the container in a new and novelmanner whereby prog tection can be efiected at low cost and theefficiency of the container as a collapsible structure is increased.

Another object is to provide simple and efficient means for collapsingthe container for the g5 purpose of ejecting its contents in desiredquantities.

A still further object is to provide a container the bottom of which isassembled therewith in a simple but durable manner whereby the seamformed at the juncture of the parts will resist normal strains to whichthe container is subiected while it is being filled or collapsed.

A still further object is to provide a container which, initially, is ina collapsed condition but which is expanded by the forceful injection ofbulk material thereinto through the orifice provided at the outlet.

with the-foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in. the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it-being understood that changes in the preciseembodiment of the invention herein disclosed may be made within thescope of what is claimed without departing from the spirit of theinvention.

In the accompanying drawings the'preferred forms-of the invention havebeen shown.

In said drawings:

Figures 10, 11 and 12 show further modifications.

Figure 13 shows in collapsed condition the modified form of containerillustrated in Figure 8.

Figure 14 is a section through the bottom portion of another modifiedconstruction of the container.

Figures 15, 16 and 17 are sections through another form of the device.

Referring to the figures by characters of refer ence, l designates acontainer formed oi a tube of thin ductil metal, the bottom portion ofwhich is produced by folding one edge of the tube inwardly, as at 2, tolap an annular flange 3 formed on a disk-like member 4. After theseparts have been assembled, as described, the space beneath the member 4and that surrounded by the portions 2 and 3 is partly or entirely filledwith a material 5 formed of metal fabric, plastic, or any other suitablematerial.

The tubular portion of the container is formed with a continuous threadformed therein by rolling or in any other manner found desirable, thisthread being indicated at 6. By extending the threads spirally along thecontainer the tube can be corrugated more readily than would other wisebe possible and at the same time it is rendered collapsible in thedirection of its length somewhat after the'manner of an accordion. 50

The top of the container is formed with a screw,- threaded neck 1 whichnormally is engaged by a cap 8 for sealing the contents of thecontainer.

While it has been found practical to form the container as shown inFigures 1 and 2 as has.

- already been described, it is to be understood that if preferred thebottom of the container can be in the form of an inverted cup 9, asshown in Figures 8 and 13, the free edge portion of this cup beinggripped within the bottom fold In of the corrugated tube I I and saidparts being bound together tightly by an inverted disk I2.

A further modification has been shown in Figure 14 .wherein the edgeportion of the container I3 is not folded but, instead, is clamped uponan inverted bottom disk I4 by a band or ring I 5.

All of the containers herein described are formed with the spiral orthread-like corrugations and all of them are initially produced in acollapsed form, as shown, for example, in Figure 13 wherein thecorrugations are substantially fiattened on one another and the cup-likeportion 9 of the bottom extends close to the neck 1. After a containerhas been formed in this shape the matter to be held thereby is forciblyinjected into the container through the opening in the neck and will actto press against the bottom of the container I, acting somewhat like apiston, stretch the tube and open out the convolutions substantially'asshown in Figures 2 and 8. Caps can then be applied and the containerscan be sold to customers for use in dispensing the contents with orwithout separate holders provided therefor.

While the contents of one of these containers can be ejected by removingcap 8 and pressing the bottomof the container toward the neck, therebycollapsing the container longitudinally, a special advantage is found inthe fact that this type of container is especially adapted for use inconnection with different kinds of holders. For example, such acontainer can be used as a refill for a holder in the form of a shavingbrush handle, one form of which has been illustrated in Figure 1.

Referring to the Figure 1, I6 constitutes a tubular body portion closedat one end, as shown at I1, while its other end is open and is reducedannularly to provide a neck I8 the base of which is surrounded by ashoulder I9. On this neck are angular lugs 26 oppositely disposed andpreferably formed with parallel inclined ends, as shown at 2|. Formed onthe bottom I1 within the handle is a boss 22 having lugs 23 on theperiphery thereof which are regularly spaced.

Removably seated in the body portion I6 is a sleeve 24 in which isrolled or otherwise produced, a screw thread 25. Each end of this sleeveis formed with regularly spaced notches 2B and when the sleeve is seatedin the body portion I6 it fits snugly against the inner surface thereof.

A cap 21 is adapted to receive the neck I8 and has an interior annulargroove 28 to which lead outlet slots 29 preferably inclined tocorrespond with the pitch of the ends of lugs 20. Thus cap 21 can beplaced over the neck l8 until the lugs 20 reach the slots 29 at whichtime, by rotating the cap, the lugs will be caused to enter the slots29, thereby drawing the cap 21 toward shoulder I9. Lugs 26 willultimately enter groove 28 so that it thus becomes possible to rotatethe cap relative to the body I6 without detaching it.

A cap 21 is formed with a central nozzle 30 surrounded by the bristles 3I of a brush, these bristles being heldto the cap by any suitable means.The bore 3I in the nozzle is counterbored at 32 so as to receive thethreaded neck I of container I.

Regularly spaced lugs 33 are provided in the cap where they will engagein the notches 26 in one end of the sleeve 24 so that the cap and sleevecan thus rotate together, it being understood that the bottom end of thesleeve containing notches 26 will be free to move past the lugs 23.Embracing lugs 23 is a notched end 34 of a guide sleeve 35 which isextended around boss 22 and within sleeve 24. Both ends of this sleeveare notched so that the sleeve can be reversed when desired. Obviouslythe lugs 23 will hold guide sleeve 35 anchored to the body portion I6while at the same time lugs 33 will engage the threaded sleeve 25 sothat it can rotate with cap 21.

Sleeve 35 has a desired number of longitudinal slots 36 and extendingslidably within these slots are portions of a head 31 which is slidablein guide sleeve 35 and constitutes a seat for the bottom of thecontainer I. These projecting portions of the head or follower 31 arejoined to a screw-threaded ring which extends around and is slidable onguide sleeve 35 but is in screw-threaded engagement with the innersurface of the threaded sleeve 24.

Normally the head or follower 31 is located at one end of the slots 36and ring 38 is similarly located. A refill tube or container I isinserted into the sleeve 35 so as to rest on the head or follower 31.This refill tube is first joined to cap 21 by screwing its neck into thecounterbore 32. Cap 21 is placed upon and joined to the neck I8 asheretofore explained and lugs 33 will become seated in notches 34 at theupper end of sleeve 35.

When it is desired to dispense a portion of the contents of the refilltube or container I, the cap 21 is rotated relative to the body portionI6. As the threaded sleeve 24 rotates with the cap and as the sleeve 35and threaded ring 38 are held against rotation by the body portion I6,it will be obvious that this relative rotation of the cap and bodyportion will cause the ring 38 and the follower 31 to feedlongitudinally of the holder, the follower pressing against the bottomof the refill tube or container and collapsing said tube slightly so asto expel a portion of its contents from nozzle 30 into the spacesbetween the brush bristles.

After all of the contents of the refill tube or container have beenexpelled the cap is detached from the body portion, the empty tube whichis guide sleeve 35 and the threaded sleeve 24 are bodily removed,inverted and reinserted into the body I6, thus bringing the follower 31,which had previously been elevated, into its lowermost position withinthe body portion. A new refill tube or container is then attached to thecap and is lowered into the sleeve 35 while cap 21 is applied. Thestructure is then ready for further use.

Another form of brush has been illustrated in Figure 8. In thatstructure a longitudinally slotted guide sleeve 39 connects a cap 40with a base 4|, there being threaded rings 42 secured to the ends of,the sleeve and screwed into the cap and base. The brush 43 is connectedto a plug 44 which is screwed into the cap 46 and is adapted to beengaged detachably by the neck I of the container. This container issuspended within guide sleeve 39 and rests on a follower 45 which slidesin the slots in guide sleeve 39 and is joined to a screw-threaded ring46 surrounding the guide sleeve.

The body portion 41 of this device has a screwthreaded lining or sleeve48 which is engaged by the ring 46. Thus by rotating the body portion 41ring 46 will be shifted longitudinally to collapse the container asheretofore explained.

If cold cream or the like is to be dispensed and it should bedesired todeliver the matter into a In Figure 12 there has been shown a holder inbowl-like container, a structure such as illustrated in Figure 9 couldbe used. Instead of providing the cap 49 with a brush it is formed witha recessed end 50 into which the matter delivered from the containerwill be discharged. This receiver formed by recess 50 can be covered orprotected by a detachable lid 5|.

Simplified dispensing means trated in Figures 10, 11 and 12. In Figure11, for example, the collapsible container is inserted into alongitudinally slotted guide sleeve 52 closed at one end while its otherend has a detachable cap 53 carrying a nozzle 5|. The neck of thecontainer is with this cap so as to deliver material to the nozzle and acover 55 is pivotally attached to the cap, as shown at 56 so as to housethe nozzle. A spring 5'! bears against angular faces 58 on the have beenilluscover near its pivot and serves to hold said cover in either closedor open position. By means of a finger piece 59' extending from thecover it can be swung to either of said positions by the thumb or afinger of the hand grasping sleeve 52. Follower 59 is slidable in thissleeve and is connected to an arcuate ring 60 which is slidable on thesleeve 52.

Instead of using a sliding ring the follower 6| can be actuated by aplunger 62 slidable in a longitudinally slotted sleeve 63. as shown inFig. 10.

This plunger is joined to a spring restrained dog 54 the free end ofwhich is adaytd to engage the inner surface of sleeve 63. By pressinginwardly on the plunger the dog will shift into or frictionally engagethe wall of sleeve 63 and advance follower 6| so that it will pressagainst the housed container l which is supported by the cap 65detachably mounted on sleeve 63. Intermittent thrusts against plunger 62will feed the follower intermittently against the container to collapseit and the pull exerted by spring 66 on dog 64 will be suflicient tomaintain the follower in any position to which it may be moved.

detachably engaged the form of a sleeve 61 formed of a spirally woundband spring one end of which is attached to a cap 68 while the other endis detachably joined to a head 69. A container supported by cap 68 canbe collapsed in the direction of its length by contacting the sleeve'6'llongitudinally.

Obviously, various other modifications can be made within thev scope ofthe present invention.

For example, and as shown in Figures 15, 16 and 17, an ordinarycollapsible tube T can be compressed by a grooved spherical roller 10advanced intermittently by a pawl and ratchet mechanism 1| operated by aspring restrained plunger I2 slidable along a slot 13 in the casing 14in which the tube is retained by a cap 15.
